benzhydryl amines from the reaction of readily available sulfone derivatives with amines is described. The Cu‐catalyzed desulfonylative amination not only provides structurally diverse benzhydryl amines in good yields, but is also applicable to iterative and intramolecular aminations. Control experiments suggested that the formation of a Cu‐carbene intermediate generated from the sulfone substrate,
描述了一种由易得的砜衍生物与胺反应合成二苯甲基胺的新方法。铜催化的脱磺酰基胺化反应不仅以高收率提供结构多样的二苯甲基胺,而且还适用于迭代和分子内胺化反应。对照实验表明,从砜底物生成的铜卡宾中间体的形成,代表了去磺酰基化转化的新途径。
